To all whom iii-may concern:

Be. it known that I, ALBERT H. TAYLOR, a citizen of the United States, and aresident of Easton, in the oounty'of Northampton and State of Pennsylvania, have invented a new and useful Automatic Oiler, of which the fol-' lowing is a specification,

' he object of m invention is to provide an automatic oiler or use in. connection with the air-feed pipe of a'pneumatic motor, and

comprises means under the control of pressure in the pip'efcr'determining the amount of oil which'may be supplied to the air within.

the feed-pipe. I y

A practical embodiment of my invention is represented in the accompanying drawings,

, Fig.

- is provided ing 7 abuts, and a lock-nut 10 engages the nut in which.

Figure 1 represents in elevation a pneulmaticmotor of the rotary piston type with my improved oiler attached to the feed-pipe" thereo Fig. 2 is a transverse verticalsection taken in the plane of the line A A of Fig. 1 looking in the direction of the arrows, and 3 is a longitudinal section'taken in the plane of the line B B of Fig. 2 looking in the direction of the arrows.

The pneumatic rotary piston-motor herein" shown is denoted by 1 and may be of any well-known or approved construotion such,

for instance, as that used for operating a drill.

The feed-pipe of the motor is denoted by 2. This feed-pipe has mounted thereon an oilreservoir 3. This oil-reservoir is free to be adjusted rotatably on the feed-pipe, so as to keep its supply 0' oil at all times in position to fiow into the interior of the feerlpipe when ermitted to do so by the controlling-valve.

his reservoir is rovided with a suitable fill 11 of the packed bearing 6 for clamping the oil-reservoir in any desired rotary position on the feed-pipe. A hollow valve-bushing 12 is screwed into the oitreservoir, and its inner end is in open communication with an annular chamber 13,whieh surrounds the pipe 2 and which is at all times in. communication idly adjusted, so

with the interior of the pipe through ports 14.- The bushing 12 is provided with a plurality of series of holes through its walls at different distances away from the feed-pipe 2, which holds opencommunication from the interior of the oil-reservoir to the'inter'ior of the valve-bushing. In the present instance four series of these holes-are shown, (denoted, respectively, by 15 16 17 1s. c 13 51.

A cylindrical valve" i9 is fitted to slide in the valve-bushing 12and is normally held at v.

the limits of its inward movement by a spring 20, interposed between the outer end of'the.

valve and the bottom of the bore in which the valve slides. A set-screw 21 is arranged in the bushing in position to adjust the limit of outward movement, of the valve 19' When the valve 19 is at the limit of its inward movement, it will. close communication from the interior of the oil-reservoir to the interior of' the air-feed pipe.

In operation when pressure is shut ofi from the feedepipe no oil will befed from the reservoir into the same] As the air is fed into the pipe 2 it willfbecause of the pressure es'-- caping through 19 outwardly against the tension of the so, and thus open one or more of the spring series of holes 15 16 17 18 for permitting. the oil-reservoir to supply a greaterd'rf'lesser amount of oil to the air within the-feed-pipe. As above set forth, it will be seen, that the amount of oil to be fed can be accurately a'djusted b the set-screw 21, so that it should be foun that it is undesirable to open-all of may be stopped in its outward movement before all-of the said series oi-holes are opened. j g

It will be seen-that the oilereonst'ruoted and arranged as above described maybe re that the valve 19 wil-l'always be below the level of the oil within the IGSBI'VOII" irrespective of the position in which the motor is plaoedfor use. It will also be seen that the amount of oilto be fed to the air within the feed-pipe iii-regulated within the holes 14; force-the valve the holes in the valve-bushing by the air-' pressure within. the feed-pipe the valve 1,9 ,9o
